Migration combinations of processor compatibility modes for active partition mobility
When you move an active logical partition between servers with different processor types, both the current and preferred processor compatibility modes of the logical partition must be supported by the destination server.
The following tables describe the processor compatibility mode combinations for active migrations. They show the processor type of the source server and the preferred and current processor compatibility modes of the logical partition on the source server before the migration. They also show the processor type of the destination server and the preferred and current processor compatibility modes of the logical partition on the destination server after the migration.
| Source environment | Destination environment | ||||

| POWER7 processor-based server | default | POWER7, POWER6+, POWER6, or POWER5 | POWER6+ processor-based server | default | If the current mode on the source server is POWER7, you cannot migrate the logical partition because the destination server does not support the current mode (POWER7). If the current mode on the source server is POWER6+, POWER6, or POWER5, then the current mode on the destination server is POWER6+, POWER6, or POWER5. |
